The tube shown in the picture is not a 6sn7 .... that is a 6as7g.
The brown base RCA tube on the lower left?
That's the rectifier tube.

This is what you are going to need to do this.If you don't have any hum or noise,I'm not sure what benefit balanced connectors will give you.Anyway,you will need to put a couple holes in back and then this board and hook it up.
I would call the company because they would have the board and can give you the instructions on mounting and hookup.
Your DAC has excellent components. Love the Jupiter caps.

Hi again Michael and thanks for the help with my arc ref 3,it's up and running again after i changed the items you were talking about,a real pain to solder those small ic's.Regarding the dac,what board are you refering to?Is it not possible to just ad a another 6sn7gt and hook it up??

So the OP amp IC's did the trick in the ARC preamp? I figured it would.I haven't seen your DAC,but I went by what it would take to convert it.You may want to call the company.

Of course it is.
I hope you have the extra heater capacity, and current surplus to your B+...and then we get into just exactly how...:)
cheers,

Friend, I would not hurt thee for the world...but thou art standing where I am about to shoot.
5u4g in a cd case thinking insane heat and pick up no problem. how about a 6ax4 or 6by5 . and get soft start.
Good Morning Gents.
Thanks Douglas for the info,i've a feeling that this unit has been a balanced unit,,as you can see on the image there is another octal valvbase that has been soldered upon.So lets assume that i have the juice for heater and the B+.

It seems balanced outputs is an option.
"SE analog outputs or XLR balanced (plus RCA as well)"
I would ask the maker.
